The United States and Japan will step up their defence cooperation to deal with the threat from nuclear-armed North Korea as tensions in East Asia remain high, officials from the two allies said on Thursday.

"He's going to have a hard time because even though he's been acquitted a lot of people will feel he's guilty," Michail said.

"But are there opportunities to rebuild his image? Absolutely, if he packages this right."

Michail, who provides guidance to sports stars and celebrities, said Tostee could consider a book deal or some kind of public speaking role, but only on the proviso that he presents a clear, very particular, message.

That message, Michail said, needs to be a kind of "fair dinkum" soul searching; there would need to be compassion and sympathy for Ms Wright's family.

"He has to face the mirror and ask himself questions about how he got himself into this situation. There's a possibility he can use this experience to make a difference to other young people."

Michail told nine.com.au he would have advised Tostee to attend Ms Wright's funeral, a move he admitted was controversial and contrarian.

Max Markson, the Sydney agent who worked with Bachelor contestant Blake Garvey, once dubbed Australia's most hated man for his reality TV indiscretions in 2015, believed Tostee should keep a low profile.

If Tostee made a TV appearance "he'd probably do himself more damage than good," Markson told nine.com.au.

"The smartest thing he can do is keep his head down and move on," Markson said, even if that meant moving abroad.

"I don’t think he'll get a fair hearing from any media outlet in the world," he added.

But Michail of Image Group International said a move overseas would ultimately solve nothing.

"Yes he can leave the country, that's an easy one. He could go to Brazil, but he's just escaping from himself. You can't expect things to go away. It will be worse long term."

The clearest insight into Tostee's frame of mind comes from a 2300-word post he made on a bodybuilding forum months after Ms Wright plunged to her death.

Until now, news organisations could not publish that message, where he lashed out at the way he was being portrayed in the media, because of the murder trial.

He wrote he would give anything to "go back in time" to stop Ms Wright's death.

"First off let me say that the death of Warriena was the most tragic and distressing event I have ever experienced," he continued.

"Knowing I was the last person to be with her, it has left me permanently scarred and not a day passes that I don’t wish I could go back in time and prevent it."
